Decalgirl.com has a platinum and a black shell for your wii, again it will void your warrenty.

it voids the warrenty because you have to disassemble your wii to put it on and once you open up youre wii nintendo will not cover future malfunctions (wether you caused it by opening it or not) i see no problem with this cause few ppl have probs. with wii.

a smarter option would be to check out the Skins from decal girl, their really good and cover all of your Wii. they have i think 11 pages of skins to choose from as well as skins for all other systems/handhelds/ipods/zunes etc. etc. cool website.
